+# Nomadro 部署说明
+
+## 服务器信息
+
+- 主机: `107.173.30.245`
+- 代码目录: `/var/www/nomadro.com`
+- 应用端口: `4003`（仅本机）
+- 域名: `nomadro.com` / `www.nomadro.com` → Caddy 反代
+
+## 不影响现有业务
+
+- nginx 仍在 **23794** 端口服务 `specials.nomadro.live`（v2ray-agent），未改动
+- sing-box 未改动
+- Caddy 仅占用 **80/443**，专用于 nomadro.com
+
+## DNS 配置（必须）
+
+将域名 A 记录指向服务器 IP：
+
+```
+nomadro.com     A    107.173.30.245
+www.nomadro.com A    107.173.30.245
+```
+
+若使用 Cloudflare，需关闭代理（灰云）或配置 Origin 指向该 IP，否则 Caddy 无法自动签发 HTTPS 证书。
+
+## 首次部署
+
+```bash
+ssh root@107.173.30.245
+export GIT_PASS='你的密码'
+export GIT_USER='eric'
+git clone -b test https://eric:${GIT_PASS}@gitea.dsx2020.com/eric/gitlab-instance-0a899031_nomadro.git /var/www/nomadro.com
+cd /var/www/nomadro.com
+bash deploy/setup-server.sh
+```
+
+## 日常更新
+
+```bash
+ssh root@107.173.30.245
+cd /var/www/nomadro.com
+bash deploy/deploy.sh
+```
+
+## 服务管理
+
+```bash
+systemctl status nomadro caddy nginx
+journalctl -u nomadro -f
+journalctl -u caddy -f
+```
